I believe this should be the equal length.

Yep, no idea where the UEL came from. You sure you looked into parts before they told you it's UEL? The car definitely sounds it has more flow, but like other member said... it does exactly look like the stock header with less restricted catalytic converter. I remember seeing a stock header with heatshield removed and I can still remember it's almost identical to these aftermarket sub $500 or whatever headers.

If you can post dynos, that would be the best way to prove the increased power!

I have an appointment to get a Dyno run later this month, there is only one shop that is open on the weekend here where i live..

They are the exact same inner diameter as the stock runners. The only difference is that the inner diameter coming out of the high flow is a 1/2in bigger

So it has a cat that is half as dense as stock with a 1/2 inch larger outlet?
That should be an improvement, but by how much?

I wouldn't order this if my life depended on it. The fitment of the dual canister Top Speed Catback was atrocious. Plus they lie about the piping diameter. This company is a joke.

Well, I'm pretty curious what the length of the runners is compared to stock. And would love to see the dyno results.

I do have a Top Speed Cat Back and fitment was nearly perfect. I probably need to adjust one hangar a tiny bit for it to sit perfectly. But I'm the only one that has noticed the imperfection. Everyone else just compliments the exhaust.

I have a complete TopSpeed exhaust system on my MR2 Spyder. Workmanship is decent. Fitment wasn't the greatest, it required quite a bit of tweaking. The header itself is essentially a tubular copy of the stock cast manifold. Any power gain is probably the result of the elimination of the precats and the utilization of a high flow main cat, not system design. As with the header on the Spyder, I'm sure this will not pass California emissions requirements if that's a concern. Any advantage this offers will be price, I woundn't expect to see performance gains of the magnitude offered by more expensive units. Hope I'm wrong!

Which catback? My dual canister was literally sitting against the rear axel and wouldnt connect to the stock front pipe, tips we SOOOO off and nearly all the exhaust gas runs out the right side. Stay away from this company.

I have the single canister dual exhaust. Pretty much the OEM design.

Burnt tip? Probably the 1 i shoulda gotten. Is it even a noticeable sound level though?

sissupr · 04-01-2014, 11:26 AM

so guys... I'm on the fence with purchasing the cat-back and the header...

can someone tell me if I will have fitment issues with either one... seems to be mixed reviews.

Yeah. It's the burnt tip one mentioned here: http://www.ft86club.com/forums/showthread.php?t=53599

The sound level is close to stock except when WOT.
