Xr6t Cat Back System...what Should I Get ?

[kdee10]

Hi all,

I am looking to add a Cat back system to my 2005 XR6t, but do not know what is the best to get, the size, and being in Melbourne, who should I trust to get it done ??

I am also wanting to add a cold air induction kit.

Adding these couple of things, nothing else will be needed to be upgraded within the car so it does not crap itself?

Appreciate any help, cheers !!

Don't bother with a cat back system, they don't increase power at all as the restriction is the cat. If you're just after a sound increase, remove the centre muffler & replace with straight through pipes or hotdogs...

Same with CAI, don't bother with aftermarket jobbies as they are a waste in the most part. Just get a hold of a F6 2nd snorkel & it will flow fine

Hope this helps.

Thanks for that advice, well would you recommend then for a couple of things to do that will give me some extra power, without having to upgrade too much.

Thanks.

custom tune at a good tuner..

eg horsepower factory, cv performance, nizpro, g & d etc... any of the site sponsors and then some...

I am in Melbourne, and the car is totally stock, who are the best people to take it to down here ?

Do you kno if the cat is the restriction in the NA as well?

PS. yeah yeah I know the lack of a turbo is the biggest restriction on the NA

The manifold is probably the biggest restriction in the N/A exhaust...

If you're gonna do it though, just do it all!!

I have 2005 ute. had a billet flywheel and 11" clutch fitted by Mal Wood in Warwick Qld. spose to handle 370kw at wheels so was my choice as only minor mods to rest of ute. had Genie exhaust fitted, standard dump pipe (this gives best torque) 3" fully stainless cat which splits into two of 2 1/2" pipes just before high flow muffler, continues to the back in the twin 2 1/2" pipes MINUS the rear muffler (no need for the restriction). nice deep rumble to note on idle, almost silent at 100km/hr windows up or down. No drone. drop from 6th to 4th and nice roar to note. As this exhaust let the turbo spool up very fast, she cut out at 5000rpm. drilled two of 2" holes into airbox and that fixed that problem. Now however it is running very lean as dyno run proved. 218kw at wheels. needs to be tuned to the injectors now. Programmers having bit of trouble cracking my computer but will achieve this sometime this week I told. Paramount Performance in Toowoomba Qld are doing the dyno tune, tell me the standard injectors will run to about 350 odd kw. I will get this done and get back here with chart proof if this claim is true. here's hoping. exhaust cost $1300, tune is $1200, flywheel/clutch cost$1500. if 350kw at wheels that will be well spent $4000 yeah
