Hey all, I really need some input here. I'm running 6psi on a jrsc and just installed a vpac less than a week ago. Everything was running fine until one day I couldn't hear my exhaust (thermal). All I can hear is the supercharger whine, and a rattle from underneath my car. I knew it wasn't my DC header bracket cause I broke that off a while back. I took my random tech cat off and it was freeking hollow!!!! no honeycomb or anything! just hollow! I put my stock cat back on and same thing... quite with a slight rattle in my thermal mid pipe. Do you all think the crap from the RT cat blew into my mid pipe and got stuck, blocking the exhaust? or did I blow something?? my engine runs fine though. nice and smooth but feels like I have to step on the gas more to get it going, almost at boost. Now, I don't run my car that hard and from what I can tell, everything looks, sounds and feels right with the engine.
so what do you think? ANY input is appreciated! I just ordered a kami header and a carsound cat. I'm getting ready to order a Brullen cat back. does anyone know the pipe size, I need to verify that it's 2.5"
oh yeah, one more thing.. what happened to my RT cat? is 6 psi too much boost for it? it's only one year old (end for this month)! you think I can get RT to pay for a new mid pipe? or refund my money?
Well if the catalyst is absent it has to be somewhere downstream clogging things up. I'm not sure what would cause that to happen. Running extremely rich can destroy a cat. I definitely would NOT boost AT ALL with your exhaust in that condition. If you are concerned that harm has been done to the engine, a simple compression check can clear that up.
The Brullen exhaust can be ordered in 2.5" if you specifiy it. Let them know also that it will be mating to a 2.5".
okay. It just occured to me to look into my freeking muffler..... and yeah, I see the guts of the cat in there, clogging my exhaust!!!! I took picures of it, but don't have time to post em right now.. I tried taking it out, but it's kinda hard and it breaks up when I try to get a hold of it with pliers. there's a bunch of pieces scattered inside there, god knows how many are stuck in my mid-pipe.
well, this is a sign of relief! glad it's not my motor! I kinda paniced over all this.. sorrry for the alarm, ya'll!
hey shark, do you know a good place to order the Brullen? I seem to be having problems with the dealers I found (in customizing it.) And, how's your 2.5" carsound on 9psi? I don't want this to happen to me again.
Am I the only one that this has happened to? I called Random Tech yesterday and they told me to check for bumps, scratches and signs of overheating... I plan on calling them tomirrow to see if they'll refund me or send me a new cat. The guy I talked to, Clay, didn't seem like he was going to accomidate me, even if it was less than a year old... I didn't bottom out on anything or abuse my car (that much ! ) I guess Random Tech just sucks cause it can't take boost. I rarely run my car hard (honestly).. I don't know... guess if I complain enough they'll do something.. cause now i have to replace or clean out my mid pipe!!! But really, what would cause the cat to break up like that? I just wanna know if I could of prevented it. wish I knew my a/f mix.
A cat can overheat if the engine is running overtly rich, and this can damage the catalyst. I'm not sure if running lean would do this. Being boosted, if tuned properly, shouldn't harm the cat at all, other than normal wear and tear. As far as I know, my Car Sound cat is holding up fine. I've had it for a year now.
I don't know of any Brullen dealers off hand. Have you tried contacting them directly?
their web site, brullenexhaust.com doesn't have any contact info, unless I'm not looking hard enough, it only has feedback for the web admin. I think I may have found one: AutoAccessoryStore.com. hope they're good!
I contacted RT and they're going to send me a new cat. If anyone wants to buy it off me, start making some offers. RT-822006 (5th gen)
okay, I took my muffler off and got 2 pieces of the catalyst out. I took a plummer snake and fished it through the muffler and the mid pipe. everything looks clear. Wonder what happened to the other pieces?!?? Guess they got blown out.... the exhaust note sounds better, but not the same as I remembered it. owell, I'm gonna replace it anyway.
I think I'm gonna give up on the Brullen exhaust. the dealers I call on their web site don't have info on it.. weird huh? and one guy was steering me away from it. another dealer wanted to charge me like $975 when another quoted me $480. I'd go with the cheaper, but I'm worried that no one can actually get a hold of Brullen! I don't even know how to contact them.. so what if I need to take advantage of the lifetime warranty they provide?
Does anyone have any ideas for me? I just want a quite exhaust with 2.5" mandrel bent piping. I've searched can came up empty handed. maybe a 60mm rsr? I don't know.... isn't there a place that I can get the custom pipe made? hmm, i'll search
If you want quiet, stick with the stock exhaust and cat. If you want to run 2.5" with a high flow cat, get used to the noise. I like it, myself.
Have you looked around for local exhaust shops that madrel bend their pipes? That would be the best way to go: custom. That's pretty much what the Brullen is, anyway, they are just some exhaust shop in Canada that happens to have a jig for the lude.
same thing happened to me
im not boosted, just minor bolt ons
i had a powercore high flow cat and i heard rattling, then my exhaust went quiet
the cat was hollow and the material from the cat was blocking my exhaust
i now have a Carsound 2.5" cat

hey shark, didn't you get your 2.5" mandrel piping from someone on here? I was reading a post and saw where you got it, but now I can't find it... I tried several muffler shops in my area and they all say the same thing, "I don't know anyone around here that has a mandrel bender." ..and I really don't wanna use regular piping. would it be better to go with a 60mm (2.3x") mandrel pipe? I guess I just need a contact for a custom made 2.5" one.
COOOOL!!!! hey thanks! this is going to help me out a LOT! they have the piping I'm looking for.. what I don't get is where they're saying PIPING only, then they say hardeware is included.. so what am I really getting? does the pipe have the flanges already welded on the pipe?
