Front pipe recommendation to prevent rasp

[magicallydelicious]

I'm collecting the exhaust parts to install all at once. I have tomei uel, perrin 2.5 over pipe, and 2.5 perrin non resonated catback. I'm not sure if it will be raspy as is, but I want to ensure it won't be. Anyone have this setup, and if so, what front pipe do you use, and is there any rasp?

I don't have that exact same setup but you already removed your resonator on the midpipe, so you might have some rasp regardless.

Either way, if you want to reduce rasp get a resonated front pipe

That was my fear. I may email Perrin and ask about potentially trading the midpipe, the system is brand new still.

The midpipe helps a lot. For reference I'm running a test muffler and front pipe with a stock header and midpipe and honestly it is just on the verge of rasp. That midpipe helps so much. But since you're running (I'm assiming) a cat less header, youd probably want to keep as many resos as you can

Two more options: the HKS dual-resonated FP will reduce rasp significantly. there's also the JDL "Ultra-quiet" FP. Name is a bit misleading as it's not really quiet; it just has a cat + resonator. That's what I use.
