i need to make up my mind on an exhaust for the 414 and i need a little help
(not going true duals) so here is my question

what catback to go with for my 3 inch long tubes but out of the cat backs what is the least restrictive???

and i have the ta rear bumper now so tips are an issue i had the b&b tri flow when it was a v6 car but its a 2.5 inch system and the tips require some cutting on the bumper for them to fit right.

i have heard that corsa sounds terrible with longtubes (but thats with factory cubes)

just wanted your thoughts
and i know the talk about true duals but a friend with a 408 dynoed his catback against his cutout and gained 11 rwhp (not worth the aggeravation of loosing ground clearence trying to tuck duals under the car)

pretty much any of the top brands are least restrictive, corsa, gmmg, borla. I have corsa's on mine with AR longtubes and ORY and I love the sound of it, with stock cubes. It does have a rasp but a bullet muffler added to the I pipe solves this and barely restricts any flow since they're flow through pipes. Someone on here had a writeup with the corsa compared to cutouts on the dyno and I think he only gained a handful of horsepower
