Bigger Car Or Front Split/dump Pipe?

[Xizor]

Hi all,

I have a 3" cat back kakimoto exhaust. I am looking at getting either a bigger cat of split front dump pipe. I cant afford both at the same time. So, which should i get first. I am leaning towards the cat as its much easier to install, but am intersted to know more.

[Mr. Oizo]

do the cat first, because if you upgrade the dump/front pipe first, the small cat will be a big restriction

[MANWHORE]

I say save up more money and do both at the same time. I just find jacking up the car somuch of a hassle. Then you have to undo the tight exhaust bolts.

well, that's what I did anyways. Did it all at once and never looked back.

Keep in mind, that the dump/front pipe might be a tiny bit longer or shorter or in the wrong place. so it might require fiddling and stuff. Mine required the cat to be modified.

so do it together.

I have my car booked in here and there over the next few weeks so i wouldnt even bother fart arsing around with either myself.

Rob yea do it at the same time! Saves on installation too (unless you have mates rates).

I see you are getting into the endless money pit of car modding.

Mate dont start me on this money crap lol. Spending money is how i deal with personal life being f**ked.

Actually i think maybe i should atleast get a boost gauge before this.

LOL - sound like me.

why do you "need" a split dump pipe?

looked into a simple turbo to cat-converter 3inch stainless pipe, and a 3inch highflow cat-converter? this combo would be less in cost (at the most, equal in cost) then a split dump pipe on its own.

JustJap 3inch stainless steel dump pipe (turbo to catconverter) = ~$220 + $20 delivery

3inch highflow cat-converter = ~$150 + delivery

both the above can be found on ebay, lol

I did my cat today with one of BATML's small body cats on a RB20DET. The amount of carbon and crap that was in the inlet of the original cat was amazing. There was atleast a half centermeter of crap embedded on the pipe plus all the crap that was clogging up the mesh.

There wasn't a huge difference in power (but noticable) but the car was alot smoother without so much restriction in the exhaust.

Dump pipe is next to go on

Also, do it yourself! Its only 4 bolts ffs

It took me about 2 hours of screwing around. The main problem was the cat back pulling like a spring toward the back of the car. Made it a bit of a pain the ass to get back together, if I had somone helping it would have been alot easier. I think swearing definately helps it to go on.

Dump pipe will probably be a bit harder. Just get a can of RP7 and a cheap socket set and go nuts

I dont have the tolerance, patience, or desire to do any f**king around on the car myself at the moment. I'd be more inclined to smash the shit out of it in personal frustration. Dont think i am kidding.

I definitely want the big cat off BATML's group buy, as for front/dump pipe... i dont really care as long as its good.
