does anyone remember seeing "test pipes" on ebay for somewhere around 40 bucks? it was sold as a direct-fit, off-road (in a maxima? ) replacement for your cat. did anyone here buy one of those things, like i did, and does anyone know how much of a power gain you would get by having a straight pipe over getting a relatively decent aftermarket cat. thanks for reading.

 

i bought one, tested both my stock cat and the test pipe, the test pipe got me 2mph+ in the traps.

 

dummy...does your test pipe make a gurgling, loose sound?...or is that just mine? i'm fairly certain mines not loose, it just sounds "cheap" or broken. just wondering, thanks.

 

mine sounds funny to but i made mine for 5$ and im still learning to weld so it wasnt pretty but i estimated 40 to 50hp gain










HAHAHAHHAAH only when your cat was completly clogged like mine was thought

 

i hate you,.. were the F are my speakers dude

 

My cat. was clogged too and I'm waiting to get a high-flow cat. Right now, I've just got a regular piece of $5 piping up there right now and it does fine? The only real problem w/ it is that the exhaust reeks up my garage and it somewhat bangs up and down, but, not much? I too noticed a slight power gain?
