filthy rasp/how to solve?

[spudley1988]

Decided to look into a custom system after a chat with 3 exhaust places and all claiming that a 2.5 inch system on a car with mb6 power and torque figures are a waste and gases wont be exiting anywhere near as fast as they could be and all stated 2 and a quarter would be a far more beneficial way to go even though im aware many will disagree with this. Also 2 reckoned that the mongoose steel would be thinner resulting in a horrible tinny noise added with the fact with the cat being out causing pops has probably burnt out the materials within the two boxes lol. I do appreciate hondas will always have an element of rasp but when the rasp begins to be louder than the normal exhaust note it isnt good lol. But booked in on the 9th of novemer so going to need to decide on tailpipe options and 310 quid for a cat back from a highly rated exhaust maker seemed magic to me when toyosports off ebay are around 100 quid cheaper.

I've got 2 1/4 inch on mine. Custom sports Cat, Supersprint centre and powerflow back box. It's not loud but you can hear it and it sounds nice. Got a dc2 mani as well.

Everything I've read our been told us the same, unless you're going for big power, you'll lose power through most of the range with a bigger system (probably a bit more power at high revs though)

Any clips of yours doctor? I'd love a sports cat but not the price lol. The chap who I'm going to said within an mb6 2.5 would be fine at around 8.5k revs anywhere else and it's a waste, instead of gases exiting quickly they would be bouncing around off each other or something. Guy was great tbf spent a good time on phone with him being taught a lesson lol
