So I just had the cat delete custom done and in high rpm it sounds really ricey! What can I do to get rid of that god awefull rice rocket sound? It sounds good in low rpm tho. The guy at the shop said it would do that for a while.... Something tells me that that's bullshit. Some one help!

 

Honestly... put the cat back on. Only way to get rid of the honda sound.

 

x2 that put back on or get hi flow cat to free those 2hp lol from no cat

 

More boost

 

Yeah i took mine out when the flex pipe broke, i hate it gonna order a new flex pipe this week and put the cat back in

 

only reason to be catless is if you have a WOT box and your gonna 2 Step it.

 

yea....that should be the only time

 

would it do damage to a hi flow cat havin a 2 step?

 

Maby I will get a high flow and weld it myself. He did such a shitty job. What Will it sound like with a high flow? Deeper? That's what I originaly was shooting for

 

just get a high amount of boost, that will drown out the raspyness

 

boost???he is a 2.2

 

yah i kept my stck DP,CAT and resonator. i just did the 2.5 over the axle with a Cherry Bomb Turbo 2. car sounds good with no rasp at all. Baffled Mufflers FTW!!

 

yeah he has a g5.....its kinda hard to turn up the boost if its not boosted?

 

its not hard if he boost it

 

x2 if I was tc or sc I would have said it in the original post lol. so Since I have the dp the way it is would it help if I go bigger res back?

 

the bigger you go with a N/A car the less power your gonna make. i would go no bigger than 2.5. your best bet is to go with a dp that has a highflow cat or just buy a highflow cat and weld it in. i know my cobalt-addiction 2.5inch dp with highflow cat...when i put a flashlight up to the one end...it came thru the other end. the stock cat...not a chance hat the light shined thru. what res do you have on it?

 

Just the stock res. He made the dp 2.5 sensor to sensor

 

your never gonna get rid of the rasp unless you put the stock cat back on. if your exhaust doesnt have a resonator on it, put that back on too. for an extra reduction of rasp, use the Vibrant Ultra Quiet resonator.

 

i didnt have any rasp when i put my dp on with my gmpp exhaust and header. but when i cut the res off....until the temp gets to about 165 or so its raspy around 4-5 grand....but then after that its fine.

 

i got no rasp with my gmpp exhaust

 

yea resonators are key
