Help me choose my exhaust
 

I just recently installed my openflash uel header and I'm really enjoying it. But I may have overestimated the difference of sound. I was expecting it to be noticeably louder than stock but it's really not that much at all.

So now I'm browsing around for my next mod...a catback exhaust. There are a handful of different brands that I have been looking at. Those include perrin, greddy evo3, trd, invidia q300, borla, and magnaflow.

My first question is will the exhaust sound much louder with my header compared to a stock header? I think this is what I have read but I'm just curious to what degree. That way I can listen to exhaust videos with stock headers and get an idea of what it would sound like with my header.

I would really like to add a deeper exhaust note with that rumble feeling but I don't want it to be ridiculously loud. I guess I'd rather 'feel' the exhaust than hear it. Maybe the Invidia q300 is too close to stock for me?

I enjoy the sounds of both the trd and the greddy evo3 but will these be too loud for my liking when coupled with my header? The borla is right at the height of loudness for what I'm looking for so that might be out of the picture. And the Perrin might be too expensive for what I'm looking for.

So what are some recommendations for an exhaust (with uel header) that is loud enough to 'feel' but not extremely loud when I'm really driving the car hard, at a price no higher than $1000 installed?

MXP, not the comp.

But installed? Spend that money on a small tool kit/jack/jack stands and get your hands dirty. A cat-back exhaust is LITERALLY about the easiest thing to do on this car.

Then I guess I've got more money for the actual exhaust! I didn't look into how to install it and figured there might have been welding and soldering involved. But if there's not then I could definitely do it myself.

evo 3 will be very loud with catless header. I mean neighbors calling the cops loud and drone is horrendous. Q300 is very quiet, almost too quite with cat less header (it's what I went to after the evo3). I would recommend a perrin resonated exhaust for a good sounding but not over the top exhaust.

This is the kind of response I'm looking for.

Ok, good to know that the q300 is actually very quiet and that the evo3 would be extremely loud with my catless header. I'll have to play some more sound clips of the resonated Perrin.

I played a quick clip of the mxp exhaust at cold start up and then idle but I didn't hear what it sounds like when revving. I do like the tone but I'm concerned it might be a bit too loud with my header. I'll have to do a little more research.

Yeah, can't help with the MXP as I have no experience with it ha ha. Good luck with whatever route you decide though!

I'm about to order a Gruppe-S UEL to go with my MXP, but it likely won't be on for a couple of weeks.

That's cool, I won't be ordering my exhaust for another month or so. You should let me know how it sounds once you get it all installed

If you want more noise, I would say keep the stock catback for now and get a perrin CAI and inlet hose. When you do that, you get a nasty intake rumble which I love.
Catback offers no performance gains, which you might have already known.

This is with the stock header, but when you pair a UELA Header while eliminating the intake sound resonators, you're going to love the sound

Oooh I like that^^ I didn't even realize an intake could make a sound like that. This is a totally viable option for me. Hmmmm.....

Check out my thread on the corsa catback. It's deep and rumbly like you're wanting.

You probably don't have a header, the corsa doesn't sound nearly as good, with a header

Yeah, the sound of the catback/header combo is what I'm looking for. Good to know that the corsa doesn't sound great with a header

I got Borla UEL and TRD catback and a motive test pipe. Highly recommend it if you want a good catback

I always wanted the Invidia N1 but it was always too expensive for my liking. Someone showed me the Spec-D tuning exhaust and it's very similar to looks as the invidia and has quality welds on it as well. Doesn't sound bad either. You can pick it up for roughly $300.

I haven't looked into the spec-d at all but I think I'd rather pay a little more and get something of higher quality. $300 seems a bit low for a quality exhaust. I'm expecting to pay nothing less than $600.

For me, Perrin or invida.

My .02, don't get a catback yet. Put that $600 toward a tune if you don't have one yet or the perrin CAI and inlet hose.

I'm running just an OFH for exhaust along with the perrin cai. And some other mods and this is the result:

I'm mainly posting this for the sound, but obviously, it's quick too :cool:

This.
Intake, Header, openflashtablet, most bang for your buck performance.

OFT and E85 tune are best bang for your buck, then header. Other than that FI.

I've got the oft/ofh combo. I would do e85 but the closest gas station is 45 minutes away. I realize that to get much more power I would need fi. But I'm mostly just looking for sound.

I thought intake doesn't add any performance increase? I've already got a drop in k&n.

Drop in is all you need. It makes roughly the same amount of power as a cold air does.

Intake won't help much in performance but it will help with throttle response and it will give your car a throaty intake noise you'll love.

Then if you want more exhaust I would swap the op/fp combo before catback.

Ok, good to know. Guess I should have skipped the k&n and gone with the Perrin cai.
@Aztec Why go fp/op before catback?

The OP/FP will yield more of the boxer rumble and actually affect performance. Catback should be your last exhaust mod and if you're happy with the sound with header, intake, op/fp then just get different exhaust tips from perrin or others and it looks great.

Ok, so I did a little research on getting a cold air intake like the Perrin one and i've determined that's not the route I want to go. At around $500 for the intake and hose I get little to no power increase compared to my drop in K&N. And I would have to remove the bumper which is something I don't really want to do. I also looked at the Injen SP but I don't want to go that route either seeing as how I will eventually (probably more than a year away) get the Phantom ESC.

So it looks like I can go with an over/front pipe combo and/or a catback exhaust. Now I'm thinking I may eventually get all three. But I guess with how small of a power increase these mods actually add, perhaps I should just go with whatever sounds best and is most cost effective.

At this point I like the Perrin exhaust and I think the TRD is decent but I'm not a huge fan of the tip shape. Any suggestions on good sounding over/front pipe combos and/or catback exhausts?

consider noise levels, once you go catless or high flow cat front pipe in combination with catless header it going to be loud with anything but the quietest catbacks like a invida Q300 or a TRD or similar very quiet catback.

couple of people i know found perrin to loud when coupled with cattless header and hi flow catted front pipe, perrins are great by themselves though.

people often go back to stock catback to keep the noise down when they go cattles header and hi flow front pipe, their is sod all power gain in a catback its just sound rearly

see basic bolt on mods guide link below

@steve99 What about a catless front pipe with catless header and stock exhaust? Maybe this is the sound combination I'm looking for.

I had a similar question a while ago. I posted some links to examples of the sound

exact sound is hard to predict so many variables and everyones opinion varies.

id check if running completly catlees draws a big fine if you get caught, difference in hp between hi flow catted and catless front pipe will be minimal, cats do cut down rasp and drone similar to resonator.

if you go that way you can always add a catback later if its not loud enough, or just add some perrin tips or get exhaust shop to source some nice tips for stock catback.

stock catback will at least be quiet with that setup and you wont attract unwanted attention from the police.

@Aztec Thanks for the link. That gave me some good resources but I'm still not quite sure what I want to do. Thankfully I've got plenty of time haha. At this point I'm thinking of starting with a high flow catted front pipe and going from there. I just want that perfect sound!

I hear ya mate. Go slow and buy parts one by one.

I'm looking into getting the ESC down the road as well, the torque increase is amazing

I have a similar setup to this, expect I don't have FT86 Speed headers. With your headers a frontpipe and a greddy supreme catback it should be a bit louder and a nice rumble.
