im going to get the rb pre-silencer and i want to know if i can bolt it after my stock 86 catback, then get 2.5 custom pipeing to a n1 syle mufler. would this system be effective and quiet at the same time? does anyone have a simlar setup? is this idea stupid?

 

Are you doing it in stages???? If so, get the parts bit by bit, then put them on all at the same time. It should bolt up to the stock, but I wouldn't waste the time putting it on there till you have it all at one time...IMO.

 

nah, i plan on gettin the rb presilencer, then going to go a mufflers shop to get it put on along with 2.5 piping from the presilencer to a n1 style muffler; single, driver side. so it will be from stock headers, stock downpipe w/ 2 precats, cat-back, presilencer, then single pipe to driver side to a n1 style muffler. would this be a logical setup? would it be a quiet one?

 

can anyone help me?

 

I don't think anything with a single muffler would be considered quiet. It that's not a problem just do it, you may like it. If not the presilencer will work before a cat-back.

I just read your post again, I don't anyone will be able to tell you if it will be loud. You still have all your cats? Don't think many people still have al of them, but I could be wrong.

Just as a reference, I had a 91na, got a presilencer and d/p (bonez) and the cheapo RX7.com $395 cat-back and I couldn't stand to be in the car. At cruising speed in 5th gear it resonanted like a ****, thought my ears were bleeding. So I put on a bonez high flow cat and it didn't really help, still thought the back glass was gonna break.

Again, I don't think anything with a single can will be remotely quiet.
